Analysis of Risk Factors for Lower-limb Deep Venous Thrombosis in Old Patients after Knee Arthroplasty

Abstract The objective of this study is to explore the relevant risk factors of deep venous thrombosis (DVT) in burn patients. A retrospective analysis was conducted for the medical records of 845 hospitalized burn patients from September 2012 to August 2017. Caprini thrombosis risk assessment scale (CTRAS) was employed for evaluating the risks of DVT. Based upon whether or not DVT occurred, they were divided into non-DVT group (n = 830) and DVT group (n = 15). Among 360 (42.7%) patients with high-risk Caprini scores, only 30 patients received color Doppler examination of lower limb veins, and 15 patients were diagnosed as DVT with a diagnostic rate of 1.8%. Caprini scores of non-DVT and DVT groups were 4.30 ± 2.71 and 9.87 ± 1.46 points, respectively. There was statistically significant difference (P < .05). As revealed by stepwise Logistic regression analysis, age, lower limb burn, wound infection, femoral vein catheterization, and long bedriddening time (>40 days) were independent risk factors for DVT. Burn patients are particularly prone to develop DVT. Age, wound infection, femoral vein catheterization, and long bedriddening time (>40 days) are risk factors. Aggressive preventive measures of DVT should be implemented.

Background Prevention of thromboembolic complications after elective lower extremity arthroplasty has increasingly relied on routine thromboprophylaxis in all patients. Not all patients are at equal risk, however, and prophylaxis is not devoid of complications. The aim of this study was to examine the risk factors for clinically relevant pulmonary embolism and deep venous thrombosis after elective primary hip or knee arthroplasty in a large patient population. Methods During the 10-yr study period, 116 of 9,791 patients undergoing primary hip or knee arthroplasty at the authors' institution who experienced pulmonary embolism or deep venous thrombosis within 30 days of surgery were matched at a 1:1 ratio with patients undergoing the same surgery with the same surgeon who did not experience an adverse event. Medical records were reviewed, with data abstracted using a standardized data collection form. Results Increased body mass index (P = 0.031; odds ratio = 1.5 for each 5-kg/m2 increase) and American Society of Anesthesiologists physical status classification of 3 or greater (P = 0.005; odds ratio = 2.6) were found to independently increase the likelihood of pulmonary embolism or deep venous thrombosis. In addition, use of antithrombotic prophylaxis was found to decrease the likelihood of these thromboembolic events (P = 0.050; odds ratio = 0.2 for aspirin or subcutaneous heparin, and odds ratio = 0.4 for warfarin or low-molecular-weight heparin). Conclusions In patients undergoing primary elective lower extremity arthroplasty, obesity, poor American Society of Anesthesiologists physical status classification, and lack of thromboprophylaxis are independent risk factors for clinically relevant thromboembolic events.

Introduction Post-thrombotic syndrome is a common and debilitating sequelae of lower limb deep venous thrombosis. Very little awareness is present about the risk factors and about the diagnosis, prevention, and treatment of this condition. Objective The objective of this study is to identify the predictors of post-thrombotic syndrome after lower limb deep venous thrombosis. Materials and methods A case–control study was conducted on all adult patients who were admitted with lower limb deep venous thrombosis at our institution from January 2005 to June 2012. These patients were scheduled for a research clinic visit, which included informed consent, data collection, and physical examination. Patients found to have post-thrombotic syndrome served as cases and those without post-thrombotic syndrome served as controls. Villalta scoring system was used to diagnose the post-thrombotic syndrome and then to assess the severity of the condition in both the groups. Cox regression risk factor analysis was performed to identify the predictors of post-thrombotic syndrome. Results Out of the 125 patients examined, 49 were found to have post-thrombotic syndrome. Risk factors found to be significant were body mass index of more than 35 kg/m2 ( n = 13, p = 0.003), history of immobilization ( n = 19, p = 0.003), one or more hypercoagable disorders ( n = 32, p = 0.02), iliofemoral deep venous thrombosis ( n = 18, p = 0.001), complete obstruction on ultrasound ( n = 26, p = 0.016), unstable range of international normalized ratio ( n = 23, p = 0.041) and non-compliance for the use of compressions stockings ( n = 14, p = 0.001). On multivariate analysis, one or more hypercoagable disorder, iliofemoral deep venous thrombosis, and non-compliance to the use of compression stockings were found to be independent risk factors for the development of post-thrombotic syndrome. Conclusion One or more hypercoagable disorders, iliofemoral deep venous thrombosis and non-compliance to the use of compression stockings were independent predictors of post-thrombotic syndrome after deep venous thrombosis. These findings will help prognosticate and prevent development of PTS in similar patient populations.

Objectives A retrospective analysis of data collected during subject screening following Japan's March 2011 earthquake and tsunami was performed. We aimed to determine the incidence of deep venous thrombosis (DVT) among screened subjects and to identify risk factors associated with the development of DVT as independent variables. Methods Calf ultrasonography was undertaken in 269 subjects living in 21 shelters in Miyagi prefecture during the one-month period immediately following the March 2011 disaster. Information regarding the health and risk factors of subjects was collected by questionnaire and assessment of physical signs. Results Of the 269 evacuees screened, 65 (24%) met the criteria for calf DVT. We found lower limb trauma, reduced frequency of urination and sleeping in a vehicle to be independent positive predictors of DVT. Conclusions Evacuees had an increased risk of developing DVT, associated with tsunami-related lower limb injury, immobility and dehydration.

SummaryThe serial use of non-invasive tests has been shown to be a safe method of managing outpatients who are suspected of having lower limb deep venous thrombosis (DVT). Objective testing has shown that the majority of these outpatients do not have venous thrombosis. A rapid test to exclude DVT in these patients, without the need for expensive and inconvenient serial non-invasive vascular testing, would have practical and economic advantages.Studies measuring the fibrin degradation product D-dimer using enzyme-linked immunoassays (EIA) in patients with veno-graphically proven DVT suggest that it should be possible to exclude this condition by the use of one of the rapid latex bead D-dimer tests.We have examined 190 patients with suspected DVT using both a latex and an EIA D-dimer assay. The latex D-dimer test used in this study was negative in 7 of the 36 proven cases of DVT. This sensitivity of only 80% is not sufficient to allow this type of assay, in its current form, to be used as an exclusion test for DVT. The same plasma samples were tested with an EIA assay. This information was used to mathematically model the effects of selecting a range of D-dimer discriminant cut off points for the diagnosis of DVT. These results indicate that 62% of suspected clinically significant DVT could have this diagnosis excluded, with a 98% sensitivity, if the rapid latex or equivalent D-dimer test could be reformulated to measure less than 185 ng/ml of D-dimer.

Aims. Colour doppler ultrasonography (CDUS) is widely used in the diagnosis of deep venous thrombosis (DVT); however, the number of scans positive for above knee DVT is low. The present study evaluates the reliability of the D-dimer test combined with a clinical probability score (Wells score) in ruling out an above knee DVT and identifying patients who do not need a CDUS. Materials and Method. This study is a retrospective audit and reaudit of a total of 816 outpatients presenting with suspected lower limb DVT from March 2009 to March 2010 and from September 2011 to February 2012. Following the initial audit, a revised clinical diagnostic pathway was implemented. Results. In our initial audit, seven patients (4.9%) with a negative D-dimer and a low Wells score had a DVT. On review, all seven had a risk factor identified that was not included in the Wells score. No patient with negative D-dimer and low Wells score with no extra clinical risk factor had a DVT on CDUS (negative predictive value 100%). A reaudit confirmed adherence to our revised clinical diagnostic pathway. Conclusions. A negative D-dimer together with a low Wells score and no risk factors effectively excludes a lower limb DVT and an ultrasound is unnecessary in these patients.
